drm: Add support for platform devices to register as DRM devices

Since this change, I can enable DRM on m68k, but it fails with:

| In file included from drivers/gpu/drm/drm_irq.c:42: | include/linux/vgaarb.h:34:21: error: asm/vga.h: No such file or directory

Now, do we really need <asm/vga.h>? It seems I can make it build and boot using:

Alternatively, I can provide an empty <asm/vga.h> (cfr. frv, mn10300, parisc, sh) or a simple (probably incorrect) one that includes <asm-generic/vga.h> (cfr. microblaze). But so far we never needed <asm/vga.h> on m68k.

For the record, this "problem" has been visible in linux-next (see m68k/allmodconfig) since July 9...
